|The answer to your question depends on which bulbs (summer bulbs may also be used to include corms rhizomes) you are growing. While many summer bulbs (such as caladium or canna) prefer warm soil and grow only in warm temperatures, others such as hardy lilies (Lillium) are planted in fall or early spring and left in place year round. Others, such as gladiolus (technically a corm) can be planted on an ongoing basis to provide continuous bloom. You might check the Q&A for the specific plants you are considering.
